Answer:
Option D
Step-by-step explanation:
Given that the number of hours of daylight in a city in the northern hemisphere shows periodic behavior over time
Let t be the independent variable and no of hours H(t) be the dependent variable on t.
Maximum H(t) = 14.4 and average =12
Period = 365 days
If we fix a sine curve for this since period is 365, we must have coefficient of t as
So the function H(t) will have sine term as sin 0.017t ... i
Since average = 12, we have
H(t) = 12+a sin 0.017t
for some suitable a.
To find a, use maximum
Maximum is when angle is 90 degrees i.e. when sine value =1
max H(5) = 14.4 = 12+a (1)
a =2.4
Hence correct equation would be'H(t) = 2.4sin(0.017t)+12
OPtion D is right answer.

Step-by-step explanation:
Let's simplify step-by-step.
6.3x10−(5)(10)−3
=6.3x10+−50+−3
Combine Like Terms:
=6.3x10+−50+−3
=(6.3x10)+(−50+−3)
=6.3x10+−53
Answer:
=6.3x10−53
i did this before the answer is choice B

Answer:
16
Step-by-step explanation:
Here we will show you how to calculate 6 divided by 3/8. We will give you the answer in fraction form and in decimal form.
Here is 6 divided by 3/8 displayed mathematically in colors:
6
÷
3
8
The numbers in 6 divided by 3/8 are labeled below:
6 = whole number
3 = numerator
8 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
6 x 8
3
=
48
3
Thus, the answer to 6 divided by 3/8 in fraction form is:
48
3
To make the answer to 6 divided by 3/8 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 3 = 16
The answer is rounded to the nearest two decimal points if necessary.
48/3 can be simplified to 16/1.
16/1 is an improper fraction and should be written as 16.
Answer: 1.0x10^9
Step-by-step explanation:
first, one million is:
1,000,000
you can count that we have six zeros, so in scientific notation this is:
1.0x10^6
one thousand is 1,000
we have 3 zeros, so in scientific notation this is:
1.0x10^3
Then, the product of these numbers is:
1.0x10^3*1.0x10^6 = (1.0*1.0)x10^(3 + 6) = 1.0x10^9
